HIGHWAY-MAINTENANCE ATTACHMENT FOR MOTOR-TRUCKS.

Specification of Letters Patent.

Patented. May 27, 1919.

Application filed May 13, 1918. Serial No. 234,239.

To all wkm it may concern:

Be it known that I, GALEN A. Goss,'a citizen of the United States, and a resident of Durand,-in the county of Pepin and State of Wisconsin, have invented certain new and.

useful Improvements in Highway-Maintenance Attachments for Motor-Trucks, of which the following is a specification.

This invention relates to an attachment for motor trucks which is particularly designed for highway maintenance work and the primary object of the invention is to provide an attachment for an ordinary mot'or truck, of any desired type or size, which may be used in lieu of the usual type of drag, planer or scraper used for properlysurfacing highways or roads, eliminating the inconveniences contingent with draggin surings, forming a part of this speci face planers, scrapers or the like behind a truck,and providing a device by means of which a much greater highway surface may be prepared, than is possible to prepare with an ordinary surfacing device drawn by horses, in the same period of time.

More specifically, this invention'comprehands the provision of a pair. of standards which are supported above the floor or platform of an ordinary motor truck and pivotall-y supports levers to which are connected supportin .hanger structures, to detachably connect t e desired type of surfacing tool to the lower end of these hangers, and to further provide an auxiliary hand lever which is carried by each of the verticallyadjusting tool levers, for varying the angle with respect to the horizontal, of the surfacing tools Other objects of the invention will appear in the following detailed description, taken in connection with the accompanying drawcation,

and in which drawings:

' having the highway maintenance attachment Figure, 1 is a side elevation of the; truck applied thereto, and having one of therear' wheels of the truck removed.

Fi 2 is a rear elevation of the truck showing the invention applied thereto, and having parts of the truck broken away.

Fig. 3 is a gerspective view of a cutting or surfacing bla the attachment," and of one of the hanger structures of the device. Referring more particularly to the drawmgs, A designates a motor truck of any ordie to be used in connection with N nary construction having a rear platform B,

and suitable supporting. girders C,

-The road or highway surfacing attachment is carried by theplatform B of the truck A, and it includes a air of blades 1 and 2 which are provided pr working the' surface of a road or highway.

The blade 1 is carried by the" lower ends of a pair of-vertical bars 3 and 4, which in connection w1th the head or cross bar structure 5 and the vertical bar 6 forms the suspending hanger forthe blade 1. The cross bar or head structure 5comprises spaced bars 7 bar 6 is pivotally connected by means of a bolt 9. Suitable angled braces 10 extend diagonally across the upper corners of'the suspending or supporting hanger structure. The vertical bar 6 has its upper end connected to one end of a hand lever 12 which is pivotally supported intermediate its ends by a standard structure 13. The standard structure 13 includes-a pair of spaced bars 14 and 15 the lower ends of which angle outwardly to form bracing legs as shown at 16, and an upper and lower vertical bar 17 and 18 between the facing ends of which the lever 12 extends, as clearly shown in the drawingsi The lower bar 18 has its lower 1 end forked and angled to form bracing legs 19. The lower ends of the bracing legs 16 and-19 are angled to' form feet which engage against and are attached to the platform B.

A quadrant 20 is'attached to the bars 17 and 18 and'it is adapted for co-action with a the hand lever 22and passes over a grooved pu lley127 which is carrled by the hand lever 12. T e cable 26 has its lower end connected toth head structure 50f the suspending hanger structure, to one side of the pivotal Fig. his a fragmentary perspective view support 9 of the hanger structure so that by the adjustment of "the position of the respect to the horizontal may be varied as hand lever 21, the angle of the blade 1 with their upper ends to suitable-eyes 31 carried by the truck structure. The rods 28 and 29 brace the blade 1 during the operation of the road surfacing device, and their connection, with the truck permits of unimpeded adjusting movement of theblade; The rod 28 is bowed intermediate its ends as shown at 30, to allow suflicientmovement of the rod,

28 which is connected to the blade 2.

A stay chain 31 is attached to the blade 1,

' by a suitable attaching bar 32 and to the under surface of the truck','asishown at 33.-

The blade 1 has a smoother plate 34: attached to the forward face-thereof at its lower'edge and if it is so desired, an ordinary cutting blade may be attached in lieu of the smoother, or the particular type of cutter blade, as indicated at 35, in Fig. 3 of the drawings. This cutting blade 35 has a relatively straight portion 36 and a forwardly curved sharpened lower edge 37 The straight portion is provided .with bolt receiving openings 38 to attachit to the blade 1. The blade lhas a shield 39 attached to the forward. surface of the same along a portion of the upper edge, extending along the upper edge of the blade from the forward end thereof, to prevent the dirt from passing over the upper edge of the blade.

The structure connected to the blade 2, for

operating the blade, etc., is identical with 'the structure relating to and coacting with the blade 1.,

The blades 1 and 2am disposed at oblique angles to'each other and to the line of travel of the trucks, as is ordinary in disposing the surface working blades of road scrapers. or

surfacing tools, and to obtain the most efiicient results.

The blades 1 and 2, are, as will be noted from the foregoing description and draw ings, mounted for adjustment independently of each other, sothat if it is desired, one of the blades and the tools carried thereby may be raised upwardly out of a ground engaging position, while the upper blade is in a ground engaging or highway surfacing position thereby permitting one of the blades to be used independently of or in conjunction with the other as desired. The hand lever 22', and cable 26 connected thereto, permit of'pivotal adjustment ofthe carrying frame, and consequently the blades land 2, to adjust the angles of these blades with respect to the horizontal, either one, independently of the other.

Having thus fully'described the invention, What is claimed is:

1. In a highway maintenance attachment for motor trucks, .2. surface working blade,
